Basically yes, especially at legendaries there isn't much variation, they anyways have the highest gear score in the game and there are pretty much fixed BiS legendaries in many cases at least based on which talent setup is used (if even).
Trinkets are for sure another beast, but there are still many where the effect is either useful or not.
Sure at both cases the stats itself are of interest also (and it get's more complicated when the effect grants a stat), but depending on how good the effect is it takes or gives value to the importance of the stat (but whom do I tell this anyways, probably the effect is already just some kind of modifier for the stat value of the given item or the other way round).
Letting those values empty and just considering the stats is for sure a possibility that at least tackles what I was talking about, but unfortunately isn't really a solution because nothing else has a value that way, which sure, is a way to look at it, but that's even to rough. You do have your basic strategies set up anyways (even while I must confess that I don't understand why the current default strategies, at least for tanks, are mythic+ based, but that's another thing and doesn't really matter anyways) where the weightings for legendaries, trinkets, relics,... are present already, even while they won't fit perfectly for sure, they will in most cases at least fit way better than just taking the stats into consideration.
When I think about it, the easiest solution would be a way to simly clone your default strategies and make it possible to alter those clones.
