Sometimes there are firmware dependencies that make that difficult.  And
even if it's just user laziness/forgetfulness, that still translates to
extra support requests.

I'm OK with saying that localbus nodes should have simple-bus in new trees,
and defining canonical compatible values (chips with eLBC should be
"fsl,XXXX-elbc", "fsl,elbc", "simple-bus").  I'm not sure what you mean by
"should only use simple-bus internally", especially in the context of the
binding.

Just add localbus to the generic table.
