[python-committers] Promote Stefan Behnel as a core developer

[Serhiy Storchaka]

I propose to promote Stefan Behnel (aka scoder on the tracker and 
GitHub) as a core developer. Perhaps not one from us is surprised that 
he is not yet a core developer. Stefan is a core developer of Cython and 
lxml, two important projects in Python ecosystem. He is a coauthor of 
PEP 489. His first patch is dated by 2010. He is not so active as other 
candidates in writing patches (I have counted less than 20 of his 
commits), but he is active on the bug tracker and mailing lists 
(reported 95 issues and commented much more). His expertise in 
XML-related issues was very important. He is assigned as an expert for 
the xml.etree package.

Maybe you can add more about Stefan's merits. This is just what I know 
personally. I worked a much with him and have very good impression about 
him.

Ah, and the PSF also just granted him their quarterly community service 
award for
2019-Q1. https://www.python.org/community/awards/psf-awards/#march-2019
