Autos, suppressors, short barreled rifles/shotguns (and others) weren't regulated until the National Firearms Act of 1934. So, no, the 2A hasn't always been restricted.
To my knowledge, there has been only one challenge to the NFA of 1934, namely United States v. Miller.
See
https://supreme.justia.com/cases/federal/us/307/174/
Summary, some feller by the name of Miller had a short barreled shotgun that wasn't registered (tax stamp) as required by the newly implemented NFA of 1934. He was arrested, went to court...all the way to the SCOTUS. Alas, he died before it was argued at the SCOTUS.
As part of the decision, the majority (who ruled for the government) stated that:
The Court cannot take judicial notice that a shotgun having a barrel less than 18 inches long has today any reasonable relation to the preservation or efficiency of a well regulated militia, and therefore cannot say that the Second Amendment guarantees to the citizen the right to keep and bear such a weapon.
I
n the absence of any evidence tending to show that possession or use of a "shotgun having a barrel of less than eighteen inches in length" at this time has some reasonable relationship to the preservation or efficiency of a well regulated militia, we cannot say that the Second Amendment guarantees the right to keep and bear such an instrument.
Essentially, because no one argued/showed that a sawed off shotgun was relevant to military operations, it was deemed eligible to regulate.
If anyone had the fortitude to show that sawed off shotguns were relevant to the military in WWI trench warfare, the decision would have gone the other way.
The understanding of "militia" in the 1930s was exactly what many have argued for in recent years (that is, if the military infantryman has it, then so should the citizenry).
Up until 1986, it was legal to ship firearms through the mail (without the need of an FFL).
Up until 1986, it was legal to purchase a new automatic firearm (with tax stamp).
See Firearm Owner Protection Act of 1986.

The 2A wasn't passed in the Bill of Rights to protect hunting, or home defense, alone.
So no, the 2A hasn't always been restricted.
There is nothing "common sense" about these proposed restrictions.
