Well, copy&paste is your friend! I can't remember me once writing, say,
those NSTableView datasource methods "by hand". And of course, here the new
PB defficiencies -- particularly the lack of global completion as was the
Alt-Esc functionality of the original PB (AKA PBWO) -- really cry.
Otherwise, though I understand the problem (been bite by it once or twice
myself) I guess the possible "solution" of having oh-so-many different
protocols for all possible different usages of informal ones would bring more
grief than advantage.
Well, if you would like that more than the current solution (I would not,
for one), DIY! Nothing prevents you from declaring appropriate formal
protocol in your own headers the first time you use any informal one, and use
it for all the next times...
