[TYPO3-core] RFC #14313: Class prefix problem in getUserObj and callUserFunction (t3lib_div)

i had implemented that in v3 (from 21.01), but problem is, that you you 
can change it for the FE, but for the BE it is hardcoded at some places 
to "user_".
An extension class usually has a prefix of tx_, whereas i only use user_ 
for conditions or independent scripts. Goal of the RFC is, to allow Tx_ 
as a prefix when e.g. hooks are called.

Sidenote: when a service is registered, that check is negated, so a 
service key must not be prepended with tx_ (or Tx_), so this could be a 
breaking change, if the userFuncClassPrefix was checked here.

Regards,
Andreas

PS: Have you ever changed the userFuncClassPrefix to something 
different? I'd almost say, deprecate that setting with 4.6 and always 
allow tx_, Tx_, user_, User_
