Old waste pipe in wall - remove or bury?

[OldKettle]

Hi,
I have removed an old sink from a bedroom, but the metal waste pipe is still in the wall.

I has planned to chisel around it, cut with a multi-tool so that the remaining pipe is below the surface of the plaster, and then plaster over. On the outside I planned to cut and cap the pipe.

Is that an OK way to do things?

Any thoughts would be much appreciated.

Personally would remove the pipe and make good the hole.

Thanks.

Removal is a bit problematic, due to tile cladding on the outside. The cladding will eventually be removed, so access for full removal will be easier then.

If I do finally remove it, can I simply core drill from the outside?

For now, will cutting and capping present any problems? If it is sealed I assume that damp won't be a problem.

My only concern would be possible entry of mice or vermin if it was left, damp shouldn't be an issue.
