I think you need to step off your soap box!  Big endian isn't going
away, and it likely has nothing to do with code bases.  Just look at
networking and telco protocols.  Everything in that world tends to
be big endian.  BE is what is understood in that world, and there's
little we can do to change it.

Demanding that they switch to LE is tantamount to you demanding that
their entire world change - it ain't going to happen.
