“remove” does what you want.  The “services” field expects a list of
services.  When using “remove” on a list of services it returns a new
list of (possibly fewer) services.  That’s exactly what you want.

“remove!”, on the other hand, mutates an existing value; you would need
to have it operate on an existing variable to mutate it.  “remove” is
much more elegant.
