It’s certainly not a substantiated (much less authoritative) opinion. 
My reading of your answer I linked in the other thread was that LFortran is more focussed on the interactive usecase. If it can be used as a fully-independent fortran compiler then there’s no reason in principle against being able to use it to package software for conda-forge, though it would likely have to outperform flang in some way, because we try to stick with one compiler per language/platform (to keep our already-large build matrices from exploding even further).
Sidenote: From a 100’000 foot view (i.e. ignoring many intricate differences/details because I just don’t know the respective projects nearly well enough) it would IMO be awesome if LFortran/flang could somehow be unified - at least to the extent that having a common infrastructure would accelerate (rather than hinder) the pursuit of each project’s individual goals (and maybe that’s simply not the case, but one can dream).
Happy to hear it!
