When I had a small lawn and would sharpen my blade with a hand file (didn’t have anything fancy to work with) I would just get it to a sharp edge again and could tell the difference between a cut and hacking. A straight edge isn’t that important, just getting rid of the rounded surface. And balance as mentioned above. When the pits and dings begin to affect that, then get a new blade (or try to balance it out, but that’s a bit more work).
If you do bother sharpening it, that’s gonna likely also throw it a bit off balance too, so make a point to check its center balance as you sharpen. Whichever blade ends up heavier, well just grind a bit more off of the end of that blade until it basically balances out, otherwise your mower will be louder and under way more stress, causing other parts to wear out faster.
But hey, I’m assuming you have your own grinder, so if I were you, I’d go ahead and try sharpening first before bothering with a new blade.
Spent a few minutes on the other side, and I can get it at angle, but to grind through all the massive dings… Is it worth it?

Looks like you got 2cm or an inch of sharpening. Get it sharpened.
