@crowell any obvious reason why one would need to have this enabled by default and thus unconditionally without the addition of variants?

[crowell]

@reneeotten they're mostly Quality Of Life improvements for the UI. I can make them non-default if that is the macports philosophy. It's just most people I know/have talked to prefer these small patches for ghidra. Let me know and I can switch it to non-default if that's more desirable.

[reneeotten]

what I meant is: why add them as variants. If they are useful for end-user I think it would be preferable to just add these things unconditionally to the Portfile. In other words, no need for variants - as I don't really see an obvious reason why someone would bot want to have this.

Variants are primarily intended for additional functionality that some people might want but would come, for example, with "heavy" dependents and thus it would be beneficial to give end-users a choice.

ah, makes sense! changing to be default.
