Frankly, I hope that we leave llvm-objcopy unchanged for #88878.
Users can request object files with sections exceeding 0x80000000, and llvm-objcopy should handle those requests as intended.
Overly defensive measures often create more problems than they solve. If someone adds a new writer, do we port this output size limiting code to that?
An optional flag for this behavior seems unlikely to be used.

Note: we did introduce a default size limit for yaml2obj (10MiB) https://reviews.llvm.org/D81258 .
The primary reason is that yaml2obj is an internal testing tool, instead of a user-facing one.
