including php extensions from Stefan Esser into pecl

Hi.

I was wondering why aren't the bytekit and the suhosin extension
available through pecl.
I couldn't find any information about this issue in the archives (the
only mention about suhosin that Stefan was proposing to add suhosin to
the pecl repository, but it didn't happen).
I'm pretty sure that he ain't gonna add his extensions to the pecl, if
he didn't do it in the past years.
Are there any moral, legal(suhosin licensed under the PHP license,
bytekit under the bytekit license which is the same as the PHP
license, except that the word PHP is replaced with bytekit) or
technical objection against adding  this two extension to the pecl
repository?
Can we do this without Stefan's explicit request? Can somebody
maintain a pecl package which is written by somebody else?

ps: For the record, I hate that I can't install everything from my
distribution's package repository or through pecl. :(
