If you don't use what others use, then you use something different.
As you don't want to use what other people use, it goes the same way
for other people to not want to use what you use. Whatever the reasons
for either party.
Wayland upstream/community/whatever cannot force neither you nor them
to do against their will.
So your only hope is to compete with technical excellence and

Up to you, indeed, on what you force down your users' throats, but the
fact is, you will always force something on them. Your users don't have
the freedom of choice to use your compositor without Wayland either.
You chose Wayland, your users chose your software.

Correct. Use each to its best effect, not all problems are nails.
If there already is a DBus based solution that just works, why would
someone write a new solution to replace that? There has to be a benefit
for replacing the old for the people using the old solution. It could
be a benefit for the end users of the old, or for the developers of the
old, but if the only benefit is for "outsiders", it gives no motivation.
