Also, take a look at this thread:
https://yhetil.org/63960cf762aec1ed2c4182f49cac66bc37fce2aa.camel@rdmp.org

and this prototype:
https://git.sr.ht/~abcdw/rde/tree/044de83e980b7038b87d27a090aef24229df85eb/src/gnu/services/home.scm#L1

It can be related to what you want to achieve, whithout modifying
