I think our default move should be to increase the minimum perl version 
because the older versions are not supported by the Perl maintainers nor 
by any of the current major server operating systems.

Merely because Interchange is in maintenance mode does not mean that we 
should leave it stuck in the distant past such that contributing to it 
requires extensive historical knowledge of what features were supported in 
10+ year old versions of Perl.

I asked for those who opposed increasing the minimum version to provide 
evidence of specific cases where this would cause real active users 
hardship, but we have not seen any replies so far.
