[Telepathy] telepathy-python update specs please

[Maksim Melnikau]

Is it possible to have updated telepathy-specs (xml, _generated python
files, etc) in next telepathy-python release? (e.g. do it in master
soon)

I could send a patch, but its quite big, and useless.

Yes, I know telepathy-python is deprecated, but now (as I understand)
there is no other variants to write CM in non-C language.

As it will be done, I'm going send patches which simplifies
implementantaion of: CONNECTION_INTERFACE_CONTACTS and
CONNECTION_INTERFACE_CONTACT_LIST.
