Investments in the comments, why not?

I am writing a comment , you need to add an attachment, and here I realize that I will have to lay it out somewhere else, and not on Habré - which is clearly “No Ice!” (C)
I understand that Habr is not a file dumper, but still why it’s impossible to enter the possibility of attaching a small attachment to the comment (picture, archivator ... tell me what you didn’t have such a need?), I think the same 300kb will be enough ...
