Here’s an article that contradicts your statement, who is right I’m not sure.
This article indicates that 34 States on their own could call a Constitutional Convention and basically set up their own rules and agenda.
The only Constitutional Convention ever held was in 1787 when the Bill of Rights were approved and in that conventional amendments were approved by the rules setup by the convention.
I would strongly support Texas seceding & taking about 28 states along with them.
That's independent of an Article V Convention.
They could do that right now if they had the votes.
But they don't, so they aren't.
Another consideration that makes a CC approachable is that all subjects up for discussion and voting must be approved beforehand. So, it is impossible for changes to be slipped in — like all the pork crappola liberals use to fill their pockets.
Here is a suggestion: all executive depts must be moved out of DC and rotated regularly around the country. Spread the tax $$ and get rid of the professional bureaucrats.
The Constitution had not been ratified at that point, so their convention was not an Article V convention for the purpose of proposing amendments. It was a "Pre-Constitutional" Convention.
