Even if they can, it's one thing indexing your own source files every night, another indexing a much bigger amount + massive amounts of branches, clones, etc. (I'm talking about github) - e.g. not practical - as there is no no clear way to say which branch (from git) must be indexed (obviously not all) - e.g. there is no encompassing "standard" saying so. That by itself is another BIG PLUS for mono-repo (and "mono"-rules) - things are done one (opinionated) way, trunk based development - but thus giving you things that you won't be able to have normally. Now indexing source file is not an easy and cheap task - it's basically a huge MapReduce done over several hours (just guessing), so there must be a reason for this to be done.
