If we provide this kind of tooling, I think that the cost/benefit
calculation on deprecation changes: If we have any syntactic deprecations

things get deprecated in one release, the migration cost is always going to
be the same. (This is of course a slightly simplified view, but close
enough.)
A practical example ...
I've just sorted out access to a new clients web hosting and fixed
things so I can actually log into the wordpress admin panel. Since there
has been no access since the previous support person who set up the site
went awall there are a lot of messages to deal with. The first one being
that PHP is out of date so wordpress can't upgrade. THAT is good to see
since I already know that the site will be broken if it HAD simply
updated as has happened on other sites! The question now is just what
process to follow to update without taking the site off-line. This is
not something the sites owner would ever be able to handle hence the
request to help out ...
In the case of wordpress, the next problem is working out just what
plugins are currently active, which ones will work if wordpress is
updated, and which may need to be replaced. But the starting point is
what will happen if I start by switching PHP5.5 to PHP5.6 so that
wordpress can be updated at all. Should I simply move direct to 7.2
which I have other wordpress sites running on and crib sheets to help
fixing the problems I have already tracked.
None of this can be sorted by using tools that fix the raw code. The
only route is via third party upgrades which relate to which version of
PHP is running. *IF* php was a lot more stable when RUNNING older code
then one COULD simply update the version and then play catch-up with
other updates, but with the current situation, one often has to fix raw
code problems to get the older stable site into a state that the upgrade
process will actually work.
Bottom line ... can I justify a decent price for the time sorting all of
this will take when there is no indication just how long it WILL take,
and then what work will be required in addition to simply removing the
nannying messages from wordpress ...
