Consistency does not necessarily make them desireable.

Then you'll need to wait until 2.8.0 is released (and no, I don't have an
estimate). And even if we'd implement your proposal you'd need to wait for
the next major version...

Some helper could be defined in additional units, but the problem with them
is that only one per type can be active at a time (Delphi compatible). My
plan is to change this though, but for this I first need to define proper
search rules for this...
