If these hidden problems have not been detected in the last months,
going on with two parallel toolchain flavours will neither reveal nor
fix them. So forcing a flavour change may seem a harsh step but will
force all ARM users to use EABI and therefore detect/report problems.

I don't get your conclusion to "remove" _untested_ parts. If they are
_unused_, they should be removed. If they are in use and are broken with
EABI, they should be fixed.

It's the difference of preserving code (and keeping it alive as along as
possible without touching it) or adapting it to evolving standards.
