It’s not the timeframe being too short, Ken. From my experience (e.g. PPL in two months, CFI in one month) it seems completely doable - as long as you have the funds and time to completely dedicate yourself to just flying (barring acft and DPE shortage). And not sure the doctor analogy is relevant, as they can be treating if not by 4th yr med school (7 years from H.S.) certainly by the next (intern) year. And, the flying public essentially has no input what experience the crew has.
One problem during the “aforementioned” timeframe would be getting, and keeping, CFIs due to how quickly CFIs were being vacuumed up during the post-covid hiring bonanza. Regionals then were hiring like crazy if you were approaching ATP / R-ATP mins. That’s what mattered.
