Broken part of Shimano RX100 rear derailleur - does it matter?

[Aston]

I've managed to break a plastic part on my rear RX100 derailleur, whilst stripping the bike to clean, does it matter?

It appears to be a cover and not structural.

Any advice. Thanks

Should be fine - I'd maybe glue it so it doesn't get worse.
