Valid points. I don’t know what differences if any the 10 has for tail strike geometry. While it’s longer, is the gear taller? Different strut compressions? But you hit on a valid point in that the fleet is used to it. While it is deferrable, if it wasn’t ready when the plane was, what should we do about it if anything?

The AP, AT, APU and many other more obscure things are deferrable especially some equipment that’s optional. However a sub fleet with something fundamental to the rest that’s missing presents a concern that’s being discussed.

I can’t imagine an airline would take deliveries of 9 figure fully airworthy planes only to park them for months or years over something like that. We’ll see.
