Yes, you use `assumeSafeAppend`:

Now, I want to clarify that you should only use this if you are
sure you are done with the data you removed at the end, as it
will get overwritten upon more appends to the array.

Thanks! I can use the unstable `remove` and then restore the
original capacity with `assumeSafeAppend` in case data can be
safely overwritten.
The inherent reason for `remove` to cancel previous capacity and
requiring new allocations is exactly to prevent overwriting data
that could be owned by something else?
