[Interest] Aborting `begin*` with QAbstractItemModels

What would be the recommended way to abort a `begin*` calls from 

I have a model where inserting/removing items can fail, in which case I 
would like to abort the removal.
What would be the best way to approach this? I've found a few rather 
useless threads regarding this online, but haven't found any hint in the 
documentation/example projects.

Is it save to just ignore the `begin*Rows` if it fails? From what I've 
seen from the source that shouldn't be the case. And simply calling 
`end*Rows` would probably result in similar unwanted behaviour.
