Who says this will be a specialized adhesive? If it works as advertised, it could be a super-glue alternative with easy unglueability. That would be an attractive consumer product; and the type of product that could easily end up on someones hands.

Earlier quoted context omitted.

This website often suggests totally bad ideas, like brittle epoxies for bonds they shouldn't be used for. The truth is nowadays you can just choose your favorite brand and they almost certainly have a correct, and good, adhesive selector. For example, for loctite, you should just use: https://www.henkel-adhesives-selector.com/

maybe, but where is the whimsy or delight in that?

Not a lot of whimsy and delight in having your glue joint fail because the delightful & whimsical website gave bad advice.

There are many different hot glues, not all have that property.

TIL. Which ones have this property, and which ones do not? How do we tell them apart? How do I identify the cheap hot glue that came with the cheap hot glue gun that I bought at Dollar General on a Saturday afternoon in 2021? It does this business just fine.

The ones that don't have the property are expensive specialized/stronger glue sticks. If you stick to dollar general you don't have to think about it.

Not all hot glue comes in stick form for use in a glue gun. When I hear hot glue I first think of hide glue for example.

One example might be ungluing a lithium pouch cell (usually polyamide film outer surface, which is a pretty low-surface-energy polymer) for home replacement. Electrically-debonded adhesives are a better option here, but not sure what the cost trade-offs look like.
