Feature Request: Warning when pasting terminal commands (like XFCE Terminal)

[MintMain21]

I recently migrated to MATE from XFCE, and I quickly found myself installing the XFCE Terminal in MATE for one simple reason. The XFCE Terminal (in Linix Mint anyway) gives a warning when people paste in text featuring enter keypresses, as every terminal, by nature, interprets this as a instant command.

Seeing as both XFCE and MATE are aimed at a similar range of users (noobs and experts alike), I think this feature should be an option in the MATE terminal as well.

And for the record, this warning can also be disabled in XFCE Terminal.

Recent versions of MATE-Terminal (or libVTE probably?) insert pasted newlines as literal newlines rather than submitting the command. Basically, now a paste won't run the command, only pressing Enter manually will.
It might be nice to have an optional warning nonetheless, but I think the security concerns are pretty much lifted, and it also helps with hidden text (e.g. from malicious webpages), where a mere warning would not (unless it would feature the actual text to be pasted).
