- hyphens are not allowed
- regex can be simplified (
([A-Z]|[a-z])->([A-Za-z])) - names must not start with an digit

This RegEx is not from me. It is already used in Flatseal.
Flatseal/src/widgets/busNameRow.js
Lines 27 to 28 in 562ddec
It is used to display the valid icon in the D-Bus edit field. If it is wrong, it should be fixed in both places.

hypens are allowed, but just on the last segment of the name

For consistency, instead of doing this here, can you move this to updateFromProxyProperty? Like I do it here https://github.com/tchx84/Flatseal/blob/master/src/models/variables.js#L86

To make this better than I currently do it, how about we officially move the definition of this esoteric regexp to this model (e.g. var BUS_NAME_REGEX = ...), and then we import this constant here https://github.com/tchx84/Flatseal/blob/master/src/widgets/busNameRow.js#L28 (instead of duplicating it)

Flatpak has a Bug that Apps didn't start when you give them Permission to talk to a invalid D-Dbus name (flatpak/flatpak#4940). Until this is fixed, it is better to block writing invalid D-Bus names. If someone does accidental use a invalid D-Bus name for global and ignore the warning, no Flatpak App will start until the problem is solved with the Flatpak cli or the overrides file is deleted.
