A recommended practice to deal with a repository with too many refs is to pack its refs with --all once, and occasionally run git pack-refs. Tags are by definition stationary and are not expected to change. Branch heads will be packed with the initial pack-refs --all, but only the currently active branch heads will become unpacked, and the next pack-refs (without --all) will leave them unpacked.
A packed refs file is just a bunch of independent lines. You can, essentially for free, add to or remove from it. There isn't any need to unpack it in order to modify it. Packed objects, on the other hand, are delta-compressed, so the objects inside depend on each other.
Older documentation written before the packed-refs mechanism was introduced may still say things like ".git/refs/heads/<branch> file exists" when it means "branch <branch> exists".

Git pack-refs is a command that consolidates all loose references into a single file, improving performance in repositories with numerous refs. This optimization is particularly beneficial for large repositories or those with extensive branching strategies, as it reduces the filesystem operations needed to access refs, speeding up various Git operations.
Does not pack reflogs or remote refs by default. Frequent manual use unnecessary; git gc automates it. Packed-refs locking prevents corruption but may contend in high-write scenarios. Patterns like refs/heads/* supported; no args packs nothing.
