Because ... see your own answer below :)

Indeed, if we want to solve this it would have to be some solution
that can leave the specfiles at peace. That's why I suggest to change
rpm's interpretation instead of adding new syntax. Maybe the above
isn't the best solution, yet, but perhaps it hints to a better
one. E.g. I'd prefer to come to a solution where only "webclient"
needs special treatment and new syntax, since that would mean touching
a dozen packages and not some thousands :)

But I feel that this is outside the packaging group's domain, we don't
develop rpm. Maybe Orion should file a bug against rpm?
