I'm trying to use hyperlinks in my terminal, which is a funny wrapper for Tmux in Gnome Terminal.
If I manually run Tmux with -T hyperlinks then the feature works. But with the wrapper I don't have a way to set that command-line arg, and anyway I'd like my Tmux to just always have this feature enabled.
man tmux says
-T features Set terminal features for the client. This is a comma-separated list
of features. See the terminal-features option.
[...]
terminal-features[] string
Set terminal features for terminal types read from
terminfo(5). tmux has a set of named terminal features.
Each will apply appropriate changes to the terminfo(5) en‐
try in use.
tmux can detect features for a few common terminals; this
option can be used to easily tell tmux about features sup‐
ported by terminals it cannot detect. The
terminal-overrides option allows individual terminfo(5)
capabilities to be set instead, terminal-features is in‐
tended for classes of functionality supported in a stan‐
dard way but not reported by terminfo(5). Care must be
taken to configure this only with features the terminal
actually supports.
This is an array option where each entry is a colon-sepa‐
rated string made up of a terminal type pattern (matched
using fnmatch(3)) followed by a list of terminal features.
The available features are:

hyperlinks
Supports OSC 8 hyperlinks.
If I add the hyperlinks feature to my terminal-features string using set -as terminal-features ",gnome*:hyperlinks" as inspired by the FAQ, nothing changes.
Is this because my terminal-features command is wrong, or is it because setting terminal-features is not enough to enable the feature? (It's confusing but it sounds like maybe -T is about enabling the feature in Tmux and terminal-features is about overriding detection of features in the "outer" terminal?)? Is there any other way to enable hyperlinks in the Tmux config?
set -as terminal-features ",*:hyperlinks" should work.
In my original question I wrote set -as terminal-features ",gnome*:hyperlinks", I don't think that would work since it seems gnome-terminal doesn't put gnome in $TERM.
For this to work you must fully restart tmux - tmux kill-server then tmux new seems to do it.
