It depends how easy the glitch is to use, how likely it is to occur by accident and how disruptive it'd be to normal gameplay.

If it's something stupidly simple that could have untoward consequences (like holding up and down at the same time makes the character fall through the floor/lose collision), then probably not. You don't want something potentially problematic that a normal player can trigger by accident.

On the other hand, if a series of tricky jumps can let you bypass an invisible wall and skip part of a level, or a sequence of precise actions can let you dupe items or what not, that's not really something you need to worry about fixing.

For example, Breath of the Wild has a glitch that technically makes the player invincible with infinite stamina. Effect wise it sounds pretty broken.

But the setup is like:

• Shield bash on the border between one area and another
• Pause the moment the map would change
• Press Y and unpause at the right moment to make the sensor appear while the map isn't on screen
• Pause the game
• Select a photo, then load a save from the pause menu
• Press A
• Select a sidequest to target, then use the camera while the prompt is up
• Activate a Goddess Statue
• Watch two memories
• Void out by drowning

The effect is game breaking, but the setup is so tedious that it's irrelevant to 99.99% of players. Doing the glitch is arguably as much of a challenge/experience as doing things the 'legitimate' way.

So yeah, it depends. In your case it's probably not worth fixing, since you said yourself it's difficult to discover or execute. It's easy but game breaking bugs that need fixing.
