While I agree with the premise, I still don’t like the house rule changing when a new level starts. (I don’t like most house rules that deviate from accepted rules, though.) I think it tries to regulate one (kind of rare) instance of a larger set of issues.
For example, as dealer, I can not intentionally stall to “artificially” raise the blinds early with the house rule, but I can certainly do that as a player. I can take several seconds or maybe even a minute to make a decision with my big stack, knowing the blinds will go up soon and hurt the shorter stacks. So, the house rule really doesn’t prevent anything, it just takes away one method of doing it.
To me, this is one of those situations in which it’s better to leave the standard rule in place (since I’m big on rules being the same across the board as much as possible) and the players/TD will self-police any angle-shooting by dealers. A player may get by with stalling one time. He/she may even get by with it twice since the situation presents itself to a specific individual quite rarely (especially with a rotating deal) and people may not remember the last instance. After that, players aren’t going to stand for it. I think the benefit of standardized rules outweigh the potential confusion of a house rule and the very small benefit of having it.
