I just ordered parts for a new bike build, using Sram eagle. I have been happily running 11 speed 10-46t cassettes with a 28t chainring, but 30 was the smallest available for the Eagle crank sets.
Granted, since they switched to a 52t big cog, that would still be lower than my current 28/46, but, since they didn’t change the other 11 cogs, it is not the same effect as running a 28t with a 10-50 casette.
So one answer to why people aren’t running 28t rings, might simply be:
Can’t get a 28t Eagle chainring from SRAM
