Agreed.

Beware: In general this is not a very persuasive line of reasoning.
If all RFEs over the last ten years had been evaluated in this way then
most of them would've been implemented by now, and the platform would be
a horrid, rotting mess of woefully inconsistent spaghetti.
Having said that, I've spent quite a bit of time over the last couple of
months hacking Python code for the OpenJDK Mercurial infrastructure, and
I've used Python's equivalent lstrip/rstrip functions more than once.
They're quite handy actually, especially the rstrip function that takes
a string argument and removes any trailing characters present in that
string.
So if somebody's going do to this I'd actually recommend adding four
methods (needed since Java doesn't have default parameter values):
String.ltrim()
String.ltrim(String charsToTrim)
String.rtrim()
String.rtrim(String charsToTrim)
Of course one can get this behavior today with the replaceFirst method,
e.g.,
s.replaceFirst("[charsToTrim]+$", "")
but that requires compiling the regex and building a matcher, which is
awfully heavyweight, especially in the middle of a tight loop.
