As long as you don't change the PPU format and the ABI, you can use and
ship a patched compiler which uses e.g. the released units. A 2.4.0 or
2.4.2 compiler hacked to do delphi like temp. releasing of interface (if
it doesn't require an abi change!) variables should work perfectly with
plain 2.4.0/2.4.2 units.
