Maybe we're talking at cross purposes. I don't mind themes lasting five levels, if that's how many levels-worth of content they have for them. I have no problem with someone following one theme for five levels, then finding another for five, and so on, if that makes sense within the story.
What does not make sense to me is having people locked into a theme for five levels, and to have themes arbitrarily siloed by level and not by - for example - finding a secret organisation or reaching a certain level of magical aptitude. If I stop my major one year in and start studying something else, I don't keep learning the contents of my original major. And if it makes sense for there to be apprentice necromancers, then the Necromancer theme should be available at 1st level - the game-design concern that that might leave too few meaningful choices five levels down the track shouldn't overrule the logic of the game world.
Well you could hand out Themes and Backgrounds and Classes whenever you want. I mean they did say that one way to play is to leave the DM in charge of when and what you get.
