One analogy would be to not roll your own crypto. You may think you got it right, but better to just go with the battle tested solution.
This is also one of the many reasons people incorporate in Delaware primarily. The law is settled and doesn’t change, people can rely on it, so they use the clauses that were litigated and have settled meanings for decades.
The way to deal with this is write the idea down with the blockers and benefits and work to enable it slowly. For instance, forgetting one of the three signatures needed would similarly doom you, so it's not all risk, it's also reward.
Almost any consultant deals with this constantly, in any industry.
An example: when I was doing basic legal assistance, we had a lot of folks who wanted a power of attorney. Many of them insisted on getting a general power of attorney. There are significant risks that such an instrument may be too powerful, and also that it may not be powerful enough. Eventually, we had a disclaimer on the back of the request form that they had to rewrite, by hand, before we would draft the instrument for execution.
But be very careful about capitalization (it's "Employee" if you refer to the aforementioned employee, not "employee"), a wrong lowercase initial letter, and you may lose a lot.
Usually you'll find that the new idea is good, in some contexts, but that exploring it surfaces new requirements and existing ones that were poorly understood. Usually there are things that aren't being done correctly now, that when documented and planned for, change the equation.
But the big benefit of outsiders isn't their ideas (though it often is), it's their ability to help cut through the insider problems. Usually insiders know what to do but are hampered by not only the difficulties, but the politics. Someone who doesn't know the conflicts can say that the emperor is naked, that doesn't magically clothe him but allows the tailor's who've been calling it out already to actually be heard and then the problem can actually be corrected.
There's really no reason to be repeating nicknames, legal entity names, jurisdictions of incorporation, addresses, and the like all over a contract.
