It is important to distinguish "multiple LoAs for the IdP as a whole, one 
LoA per user" from "multiple LoAs per user".  The former, it seems to me, 
is going to be the case in any organization of any significant size. 
Multiple LoAs per user is definitely trickier and less obviously needed, 
though still relatively common (e.g. at my university many people have 
two-factor devices they use for more sensitive apps in addition the plain 
old username/password they use for all other apps).

I don't know that I agree with your concern above in general, though.  Our 
users have some kinds of "administrative access" to their accounts (update 
mailing address, eg, or change password) via LoA2 (-equivalent) login. 
This doesn't affect the quality of their two-factor (LoA3-equiv) login, as 
far as I can see.
