mainline inclusion from mainline-5.4-rc1 commit e742bd5cb55ec0be48c5e7b356393a708e7f73c9 category: feature bugzilla: 38688 CVE: NA
---------------------------
Json has limited accuracy for numbers and can silently truncate 64bit values, which can be extremely confusing. Let's consistently use string encapsulated values for json output.
While at it, convert an unnecesary f-string to str().
