So you're saying it's better for Castlevania to take the "Zelda route" by making all future titles stand-alones, and just drop the idea of linked saga altogether?
Dave Cox could've easily placed LoS "sometime in the 12th century," just like how IGA put OoE sometime in the 19th century. In fact, you can possibly fit dozens of games in the 12th/13th/14th centuries, so the idea of the canon timeline running out of slots is ridiculous. Developers won't have to deal with any story problems, because Dracula won't be the main enemy, and they can introduce a shitload of unique enemies/plot devices.
On the other hand, if a producer wanted to set a game in the 16th century to take advantage of whatever gameplay/story mechanics he comes up with, only thing they'd have to do is print "this is a stand-alone story" in the manual or box, not set the entire series that way.
-I never said better. I think both are fine ways of doing a series. I enjoy having a continuity, but at the same time I won't get angry because somebody decides to make a game that doesn't fall into the continuity.
-Ok, so all the time slots haven't been filled. That wasn't my point at all, but Dave Cox really couldn't have fit Lords of Shadow into the current canon without changing the plot. For one, Gabriel wouldn't be who he is now if he had to be shoehorned into the "official" canon. Secondly, if the plot really does include Dracula or involve Gabriel turning into Dracula like many believe, this is doubly so.
There are still rules that have to be followed. Dracula can only be fought at certain times. 11th-15th centuries cannot have Dracula as a villain lest the main character loses, and anything beyond the 18th century can't have Dracula or Belmonts at all. Belmonts were not vampire hunters before Leon, and they can't have any origin stories after Leon because the clan has already been established. The Vampire Killer has certain restrictions as of its usage, nobody else can tell a story of the origins of Dracula, nobody can have a plot with Dracula in the future because he's Soma, Alucard is asleep from 1476 to 1797, etc, etc, etc. I could go on. These are all features that limit the storytelling of a potential game.
You say nobody will have to BOTHER with Dracula, like it's a burden, but I can imagine most people who develop a Castlevania game are going to want to have Dracula in it.
-That's just as messy. Then instead of a few timelines, you have a bunch of "stand alone" games.
The reason nobody in the history of video games has ever bothered to put "this is a stand alone game" on a box is because, frankly, the game does that itself when you play it and realize there are contradictions with other games. Largely the only people who actually care that everything does not fit in a nice neat package are the people who seem to have some odd desire to have everything they play validated by some company in another country as part of an arbitrary "canon".
Think about it. If Konami never made a single other Castlevania game that fits in with the current "official" canon, does that make those games any less legitimate? No. They have their own canon. In essence, there would be two canons. One that relates to the "old Castlevania" and one that relates to the "new Castlevania". Both would be equally official, as they would be sanctioned by Konami, but neither would be part of the other.
