Investigate switching pybars to a permissive LICENSE #8

LGPL is not permissive and it's compatibility usability on python projects (and whether it may trigger the derivative clause) is murky (urwid/urwid#41 (comment)). Twisted switched off it because LGPL is ambiguous.

I looked everywhere for proof / support LGPL wouldn't trigger a derivative in python, and I came up empty. One of the reasons why it's an issue is in python a user may end up subclassing the code from source.

This is in Canonical's hands however, if they're not willing to license this permissively it may be better rewrite something from scratch in BSD / MIT.

Yeah, unfortunately Canonical seems to have abandoned pymeta and pybars.

I have been looking at adding compatibility with Handlebars 2.0, and I am thinking a good rewrite from scratch with an MIT license may be in order. This is another item to add to the list.
