The designer sends raster icons in svg. This is fine?

Question

Icons

I work (as a programmer) on freelance in a team, we make a website.
The designer was given the task of drawing icons. Just in case, I clarify for the team that icons are needed in svg. As a result, the designer sends an svg containing Raster images (not even 72dpi, but aliased 54 dpi). Everyone is ok. Nobody has any questions.

Is this a normal operating time and should not be bothered? Or is the Titanic already sinking and it's time to run to the last boat?
Share your experience please. My hands drop after this. Bitmap, damn it, svg...

Answer 1

nonsense of course. If it suits you, it's fine, but I would leave.
