Taxonomic Split 87855 (Guardado el 17/01/2021) has two possible parallel systems here: accepting Agaricaceae broadly, and folding in Lycoperdaceae, or accepting it narrowly and acknowledging three additional families. The latter option seems to preserve information the best at the moment. See:

Why has this split been made? Is there any scientific basis? As far as I am aware the latest literature all direct to keep this all together.

It's all a matter of choice. One family with five well delimited subclades, or five families all closely related. We have been maintaining Lycoperdaceae as separate anyway.

Well, that's the thing; it is not really a matter of choice. As you can see in Varga et al (2019) and Sánchez-García et al (2020), if you apply these splits you are creating polyphyletic groupings. However, maintaining it as Agaricaceae, keeps it as a monophyletic group, which is preferred.

In the first reference, the tree is not clear enough to make much out other than that they accept Agaricaceae and Lycoperdaceae. Looking at the second reference, the five families are definitely monophyletic. The only possible issue is Micropsalliota, though it doesn't look like the type species was included. That lineage might be another family, but it isn't clear what would go in it. You can also note that the two papers seem to contradict each other; the first recognizes Lycoperdaceae as a separate family, which the second seems to indicate makes Agaricaceae s. str. polyphyletic (without exclusion of the Micropsalliota clade).
