Notification suggestion

Why don’t we get notifications when we get our comment liked?
It can be a lot of likes one comment gets but there can be like a limit as to how many notifications per 1 comment you get.
It would be cool, i think, to get reminded of an old comment you left and seeing someone liked it, even getting reminded of a recent comment would be cool.
I mean now one of you comments can have 100 likes and you won’t know unless someone replies to it.
What do you think?
Would it be hard to implement?
