I just went out to weed the base around around my Idaho Locust (probably 5 years old). I saw that the bark is splitting off from the inside of the tree trunk. This is the first time that I've noticed this---I am definitely hoping that this isn't an incurable disease or something like that.

Hi Paul! Your locust tree looks severely damaged...
I would carefully remove the dead bark to see what is happening...and check for any live bark...and definitely check for beetle larva markings on the inside of the dead bark....
I have attached a couple more pics here. I can't see too far inside, and I'm not sure what beetle larva markings look like.
Should I just peel off the bark that is coming off? I've never done anything like this before.

Definitely remove all the dead bark to see where the live bark is!
My feeling is the the tree is mostly dead and you will need to remove the tree...
Too bad... I'll remove some of it this week and post an update. Fwiw, about 2 thirds of branches have blossoms on them. Don't know if that is relevant or not to this...

That is a good sign that the tree is still holding on ...but do remove all the dead bark back to where it is still alive...and remove any dead branches to clean it up.....

Be careful not to pull the bark...you will need to cut it using a sharp knife or axe in sections back to live bark!
I guess I have another question. Does whatever is left on the trunk, look healthy enough? The weather here in southern california desert isn't getting below freezing, it is generally in the 40s overnight low, if not warmer.
Also, when I trim the branches, they are all on one side, like in these pics.
Is it ok if I trim each non-blossoming branch down to where it branches out from the trunk? Or would that be going too far?

You have been busy! I'd use a sharp knife to trim more of the dead bark back to live bark...you will notice the difference.
Looks like half the tree is dead and you can remove all the dead branches....back the the trunk...
Best to burn the bark to kill any pathogens, and diseases that can still spread ...best not to bury it!!
OK, I'll use a blade, cut back the dead branches to the trunk, and then burn the removed trunk.
Is there something in the technique of using a knife, to remove the dead bark from the trunk? I mean, what is the problem with simply pulling it off?
