Anyone mash in their boiler?

[TRK41]

Its kinda a general still question lol. But last night i was just sippin a few dunkles and was thinking about my brewing/fermenter situation and thought, can i actually mash in my boiler? It would save a metric ton of steps and would give me the opportunity to distill on the grain for whiskies, gins, and things i want to retain flavor from. I know with things like corn I would have to be temps up then mashed but straining seems like such a pain and distilling on the grain just makes so much more sense. Am i alone on this? Any feedback is welcome
