Not *for key with modifiers*, but during lookup in keymaps. There are 
enough keybindings that include keys without modifiers. It is a 
recurring confusion that appears in every discussion of related bugs and 
in mailing list threads, e.g.
<https://debbugs.gnu.org/43830>
"keyboard layout handling incompatible with rest of the OS"
Perhaps it is impossible to achieve in terminal frames.

Modifier-only gestures sounds like a different feature though.

Cecilio, in the case of severe resistance you may consider another 
approach: sniff keyboard events at lower level (xinput2? IBus plugin?) 
by a dedicated daemon and emit D-Bus events that may be interpreted by 
Emacs (and other applications). The bonus is support of Emacs frames 
inside terminal applications. Isolation of applications in Wayland may 
be a trouble, but perhaps some compositors support configurable gestures 
out of the box.
