I've always disliked the convention name Good/Bad 2nt, it's confusing as there is nothing Good about it, you have a Bad hand and are wanting to get out at the 3 level without getting partner excited.

Btw, there is (of course) a variant called bad-good in which 2N shows the strong hand (with no inference about stoppers) while 3C shows the weaker (bad but not really) hand.
The version I prefer is one where 2NT shows either a bad hand (distributional with at most 12-13 HCP or so), a direct 3-level bid shows extras but is NF (approximately 14-17) and the GF hands
also bid 2NT but then bid on if partner accepts the relay. This way the 2NT is either 'bad' or 'good', hence the name Good/Bad 2NT.
There are many versions that are slightly different - weak passes, constructive bids at the 3-level, strong bids 2NT (sometimes called 'Reverse Lebensohl'), or weak bids 2NT, strong bids at the 3-level, constructive has to round up or down (sometimes called 'Lebensohl'), or even (very) weak passes, slightly stronger bids 2NT, constructive NF bids at the 3-level and very strong starts with a double (or unassuming cue bid, if that is your partnership agreement). If you call all of them Good/Bad, or if you are only familiar with some of these, it is not surprising that the name seems out of place.

All this raises another question. Do we add a bandage convention , which likely won't be used often and vulnerable to forgets or do we practice disciplined bidding and add the gadgets when we are competent in our standard bidding.

My experience with the aforementioned partner was that this situation where G/B applies came up surprisingly regularly. And they forgot it every single time

But at the same time, they also forgot every time that bidding at the 3 level required extras either way, so the hands often turned out badly regardless of whether there was a convention in place or not.
2NT is such a nonexistent natural bid in this sequence, so remembering to pass isn't much different than remembering to bid 2NT. But if you can teach your partner to pass the distributional hands without extras then you'll have made more progress than me

My experience is also that this convention is almost always forgotten, despite coming up very often. I would recommend
not playing Good/Bad 2NT (regardless of your choice of flavour) while there is still lots of room for improvement in the rest of your agreements.

I can certainly share your frustration but then I've inflicted the same on my partners while I learn new conventions.
I'm actually not hoping to "teach partner to pass the weak, distributional hands" but rather to improve our hand evaluation and understanding of the auction, bid, or pass.

. I think it's the "rules" that we learn at the start that make progress very difficult.
I have gotten a lot of mileage out of some books and written texts, some of which are available for free in digital form (but most are not). If you would be interested in some suggestions I'd be happy to recommend some places to start.
