(Although Roan's suggestion of also folding things
like {{CURRENTYEAR}}
and passing their expiration time to the cache may also be worth
considering. We could then just treat e.g. {{SITENAME}} as having an
infinite expiration time, and any truly uncacheable magic words as
expiring immediately.)
When using CDB, the cache is constant. You can't do incremental
updates. And what if WMF uses *single* cache for all projects? Then
{{SITENAME}} wouldn't be constant anymore, and we would not get better
performance where it is needed most. It could help other MediaWiki
installations a bit, just how much... I don't know.
