Reads stored settings via get_network_option(), cached per request but not free on a cold cache.
No loop in the body: the same number of instructions runs whatever you pass in.
Executed per call on PHP 8.4. The body compiles to 10.
Nothing here hands control to plugin code.
1 place in core call this, so the cost is paid more often than your own code shows.

Further down the call graph this can also reach query and transient — those are the worst case, several calls deep and usually down an error path, not what a normal call pays.
What one call costs · 1 distinct outcome
One number would be a lie: the work depends on which branch runs. These are every distinct cost WP_Application_Passwords::is_in_use() can have, taken from its control-flow graph on PHP 8.4.

Oldest PHP that compiles this body: 7.4. An instruction is not a fixed amount of time, so a version with the same count is not necessarily the same speed; what the count rules out is a difference in the work itself.
