Current configuration on the wiki

== Background
When file dependency information is lost, the startup module computes
a hash that is based on an incomplete summary of bundled resources.
This means it arrives at a "wrong" hash. Once a browser actually asks
for that version of the module, though, we rediscover the dependency
information, and subsequent startup responses will include arrive once
again at the same correct hash. These 5-minute windows of time where
the browser cache of anyone visiting is churned over are not great,
and so we try to avoid them.
The status quo is the dedicated module_deps table in core with no
expiry. This means a potential concern is building up gargage over
time for modules and extensions that no longer exist or are no longer
deployed on that wiki. In practice this has not been much of an issue,
we haven't run the cleanupRemovedModules.php or purgeModuleDeps.php
scripts in years. Once in 2017 to fix corrupt rows (T158105), and
once in 2020 to estimate needed space if we had expiries
<https://phabricator.wikimedia.org/T113916#6142457>.
Hence we're moving to mainstash via KeyValueDepStore, and not to
memcached. But for that we might as well start using experies.
To not compromise on losing dep info regularly and causing avoidable
browser cache for modules that are hot and very much still existing,
we adopted `renew()` in
