I actually tried to use Pecan and even created a couple of PoCs, but
there due to historical reasons of how our API is organized it will
take much more time to implement all workarounds we need to issues
Pecan doesn't solve out of the box, like working with non-RESTful
URLs, reverse URL lookup, returning custom body in 404 response,
wrapping errors to JSON automatically, etc.
As far as I see, each OpenStack project implements its own workarounds
for these issues, but still it requires much less men and hours for us
to move to Flask-Restful instead of Pecan, because all these problems
are already solved there.
BTW, I know a lot of pretty big projects using Flask (it's the second
most popular Web framework after Django in Python Web community), they
even have their own "hall of fame":
