[wp-hackers] load_plugin_textdomain()

[Otto]

Gotta agree, this was done wrong. A new function should have been
created instead of adding extra parameters. With the deprecated code
marking in 2.4 and up, plugin developers using debug mode would have
ample warning that their function was going to be deprecated and then
would be able to transition naturally. Instead, you've just shoved
back the problem until 2.7 or 2.8.

I highly recommend making a new function entirely and deprecating this
one entirely, and doing it now, not later.
