Kind of a similar story that one of my friends did a few years ago- went compact mirrorless instead of good old DSLRs. To my question as to what he does whenever he gets a gig here and there, he said he goes out and rents a DSLR and glass.
Suppose this works for some folks out there, but I prefer to know my gear inside and out and to have my main cam be my best cam no matter what. Renting per job kinda seems like a hassle as well.
