documentation needs to be improved to clarify the purpose of the work in light of recent developments

[wchristian]

None of the objectives in the issues in this repository state a purpose, so for all of them the question is open as to "why should this work be done?"

According to mailing list and IRC traffic the answers are:

• make the test suite stricts/etc. compatible
• try and figure out how much of cpan gets broken and once we have that data, try and convince people to make strict and friends default for unversioned code

The second needs to be documented in the defaults proposal page as linked here: https://www.nntp.perl.org/group/perl.perl5.porters/2020/08/msg258246.html

And once done all objectives need to link to that page as their justification.

I've adjusted https://github.com/Perl/perl5/wiki/Defaults-for-v7#intro to make it clear

One or more audits of these defaults against CPAN must be done in order to understand how much of it would break if each of them is chosen.

The list of defaults is currently a proposal and will be revisited after gathering some metrics.
