My impression is, thirty bees could implement everything imaginable and people would still lament about "not moving anywhere".
Actually, that's a situation I didn't expect when picking up work for thirty bees. About everywhere else, derived/forked projects are seen as pretty much equivalent to the former version. OpenOffice moved smoothly to LibreOffice, people happily tried ecgs-gcc in besides or favor of gcc, MariaDB is welcome for MySQL users, Ubuntu comes with a whole lot of derivatives, Ubuntu its self is a fork of Debian and very popular, and so on. In general forks are seen as an enrichment of the choices one can make rather than kind of a threat.
Something is different with merchants.
