This suggestion will not be popular with the City or with Cyclists. Aesthetic issues are part of that, but also the perception that the posts are inadequate for purposes of cyclist safety (easy'ish for large vehicle in particular to run over on purpose or by accident).
How would you feel about this design on Danforth that incorporates a mid-block loading zone which can be used for deliveries or for accessible loading/off-loading?

You can see that room has been set aside that doesn't block traffic (it replaces parking) and the cycle track temporarily rises to sidewalk/curb height only for that specific spot.
This design is contemplated as part of many cycle track projects on wider roads, where gapping parking can afford the space while maintaining both the cycle track and vehicle lanes.
It wouldn't be available on every block, but would be available mid-block in larger blocks.
PS, the one here is temporary, but permanent designs would be built with reconstruction.
This is generally being done at bus stops as well.
