staff_t is a "unpriv user" and so "userdom_unpriv_user_template()"
applies to staff_t.
this template has two booleans: user_tcp_server and user_udp_server
these booleans currently allow unpriv users to bind tcp and udp sockets
to generic ports respectively.
This is old, inaccurate and outdated. Instead those booleans should
probably be modernized:
tunable_policy(`user_tcp_server',`
corenet_tcp_bind_generic_node($1_t)
corenet_tcp_bind_all_unreserved_ports($1_t)
')
tunable_policy(`user_udp_server',`

I would associate a "bin_home_t" with ~/.local/bin and only allow that
to be executed, rather than all of ~/.local
But regardless this, or similar rule should apply to
userdom_unpriv_user_template() instead. Use the templates.

Modernize and use the existing user_tcp_server and user_udp_server
booleans in userdom_unpriv_user_template() instead? See above comment.

This is already allowed conditionally in userdom_unpriv_user_template()

It's not very common. Did you add this for ~/.local/bin?
