I have never had a problem distinguishing Unifont zero from Unifont capital letter O, and I prefer having no slash in a zero. However, I have received multiple requests for a slashed zero from people who have had trouble differentiating the two glyphs (who are not anonymous, at least not to me).
I made the slash less prominent than in U+00D8, and have no difficulty differentiating between that and the digit zero. But if you have a hard time figuring out one from the other then it is a problem at least for you.
If there is a lot of objection to the slashed zero I can un-slash it again (which is my personal preference). Or I can nip the single pixel of the slash that sticks out on top and bottom on the zero. That will further distinguish it from the slash in U+00D8, which extends outside the oval of the letter. This will be the hex code for zero in that case:
0030:000000001824464A4A52526224180000
You can see what I consider the prototypical slashed zero example from the granddaddy of zero slashers, the ASR 33 teletype, on this web page:

I would not just have a dot in the center, as that would look too much like Theta (Θ), and a lowered slope might be mistaken for theta (θ).
I don't know where the context would not make it clear whether something was the digit zero or an upper-case slashed letter O. Maybe: "To 0 Ørsted or not to 0 Ørsted? That is the question." Can you provide an example where it would be impossible to tell which was intended from context, in any language that uses 'Ø'?
I will be preparing another Unifont 9.0 release. I am going to redraw at least one Plane 1 script, and it will be after I finish with that. I didn't have time to do that for this release. I will leave this open for discussion in the meantime.
