My personal opinion is while I understand the reasoning behind, my concern
is about the community support. We don't have a lot of contributors at the
moment, and if we would like to modify the default limit, I'm pretty sure
it would take a lot of time for folks at least reviewing some changes that
are not really priorities...

Also, as said by some folks, changing the default would also create some
problems for some of our contributors and eventually, if some projects
would accept 119 characters while some others not,  it would also be a new
community difference between projects... (and yet again some new nit that
new contributors need to understand)

Sorry, -1 for those reasons.
