Both in-tree consumers of uprobes (ftrace and perf) are capable of task filters.
But the thing is, dso:sym is very much not a task property, adding task filters afterwards sure makes sense in some cases but it should not be the primary mode.
If people really want to optimize this we can easily add a few bits of task state which could tell the trap handler to not even bother looking up things but restart as fast as possible.
