I agree - we also had customers who used this - but that was may
years ago, and I haven't seen any such request for at least 5 years,
probably more.

I think we should move on and not get ourself stuck in "maybe
someone still needs it" compatibility issues.  If such users still
exist, they can speak up here, and offer to cover the needed efforts
to add and maintain such a compatibility layer again.

I would not hold my breath waiting for such volunteers, though...

Best regards,
