lets look at the other side of the coin....
your choice of construction is going to capture the glass and if the glass were to get broken you either have to break the frame or recut the frame so the new glass drops back into the frame from the back...
you could leave say the outside stile loose (screwed into place and not glued to facilitate glass replacement...
or you could cut your frame to accept the glass in real world fashion but cutting a stepped rabbet......
and you can sill any seen profile you wish...
