The bulk update request #1374 is pending approval.

create alias isometric (126) -> isometric_view (0)
create alias isometric_projection (0) -> isometric_view (0)
create alias isometric_perspective (0) -> isometric_view (0)
create alias isometric_viewpoint (0) -> isometric_view (0)
create implication isometric_view (0) -> high-angle_view (22703)

Reason: Merging into isometric_view a la high-angle_view, low-angle_view. Also brevity.

Might make sense to use isometric as it’s a shorter tag and appears to be the only one really in use.

is shorter, but isometric_view is more specific and follows the existing pattern of *_view found in tag_group:optics#angle.

I think it should be better to alias everything to orthogonal_view instead. First as far as I know isometric view is a type of orthogonal view, second it's easier to tell when something is in orthogonal view than when it's on isometric view... I'd say.
