I hate it when
ResEdit prohibits me setting "bundle" bit on folders, presumably
because it didn't make sense back in time when ResEdit was designed.
[It doesn't allow me to set dates on folders which made perfect
sense even at the time.]
ResEdit is not a relevant example. I'm not designing an application with an
eye toward ensuring it's still useful 10-15 years after I stop developing
it. If they've officially deprecated the name lock bit, I'll take out the
option to read and set it. If they change their minds later I'll put that
stuff back. Then I can list it as a new feature in the next release. ;-)
