I expect packagers will choose to maintain compatability
It seems fundamentally wrong to me to give "packagers" an option to make
RCS completely different, 100% incompatible with every existing usage of
it. It will just cause endless hassle if anyone is ever stupid enough
to use it. I implore you, do not do this.
You have convinced me (thinking about Debian and docs did the trick).
I will drop this misfeature shortly.
