What is the problem with supporting Linux 2.6?  Do we need to rely on
newer features? (which ones?)

I'm sure some people will want to be running Python 3.7 on RHEL 6 or
CentOS 6.  After all, there's a reason RedHat provides 3.6 builds
for it.  Of course, you may say it's RedHat's (or other vendors')
responsibility to apply compatibility patches.  But if the
compatibility code is already there, maybe it doesn't cost us much to
keep it?
