DMG Spell Point variant works with Spellcasting, not Pact Magic.
By letting Warlocks use the Spell Point system (so a 5th lv Warlock has 10 points per short rest), it enables them to still utilize low level spells without hesitation. More flexibility.
Your thoughts? At first blush I think it’s less of a problem for warlocks than anyone else.
The main difference in spell points is it essentially lets you combine lower level spell slots into higher level ones. So your sorc can turn a 1 and 2 into a fireball. Warlocks already do that. +

What it would let warlocks do is break their higher level slots into multiple lower, increasing their casting flexibility particularly for 1st and 2nd level spells that don’t scale with up casting in a way they want to worry about.
Spell points is all around more powerful. If your table is good with that, go for it!
Honestly if they aren’t taking short rests, its probably fine. Just keep an eye on how much easier if at all they start negotiating encounters and obstacles.
Warlock using the option will probably have a less explosive impact.
