Comment (by azaozz):

 Right, DB writes should never happen on front-end requests. This can cause
 big problems on busy sites especially with more complex hosting setup, DB
 replication, etc. They can go down easily.

 There is another patch in the works (afaik) for this exact place (where
 plugin files are included). It's for prevention of loading of known
 incompatible plugins (fatal error protection). Any solution here would
 have to be synced with the other patch. This is also the reason it was
 left unfinished.

 Looking a bit deeper: currently there are some problems with loading of
 plugins with unmet requirements. For example a plugin that requires newer
 version of WP or PHP cannot be installed from the UI (the plugins repo/API
 doesn't allow it) but can still be installed from FTP or SSH. These
 methods were somewhat popular few years ago, especially using version
 control to deploy changes, so thinking WP should guard against errors
 there too. Will open a new ticket for that.
