I want to properly vent a remodeled basement bath

When trying to get up over the edge of the footing, you can cut a notch in the footing and/or come out the the floor at a 45 and then back to vertical in the wall. If you use a 90, you are making a flat vent, which is a no-no.

Ok. Is there any danger to cutting a notch into the footing? I'm thinking no because you're advising it and it would be a very small section of footing.

I would try to avoid it, but others seem to do it without any hesitation.

An alternative would be to bump the framed wall in a few inches (moving the shower with it) so that there is room to run the pipe up at a 45 past the edge of the footing and still come into the wall.

edited to add- the flat section of vent in your linked photo is still not going to cut it. Vertical, down to 45 degrees is ok. No less.
