Ditto. Mach 4 hobby is not crippled, I’ve been using it for two years. Much better than Mach3 (but much smaller installed base).Maybe I don't push it very hard but in the last 18 months I have found no limitations in Mach4 Hobby. Works great for me.
Which of those industrial features do you actually use? They are mostly there so OEMs can customize it. You can write all the custom macros you want, you have access to far more inputs and outputs than most CNCs have. It is plenty for home CNCs.
