yes, right in this second. that's not what i call a strategy.

we already *know* that we have to do at least minimal maintenance of
them. users have *told* us so. and for that matter, it's some very
creative interpretation of the backwards compatibility promise to say
that removing entire modules doesn't violate it. we tried to weasel out
of that by saying they could continue to use the old versions with new
qt releases. we (predictably) failed at that, so we have to deliver an
alternative.

so any reasonable calculation of pay-off assumes these modules' presence
until qt6.

why do you think that we'll *ever* have more time for that than right
now? especially given that it will be *more* total effort if we take it
out of the general process?

and that doesn't even consider the user perspective on these pseudo
releases ...
