it's because in my limited perception display stuff is not part if the par -)

eh .. not sure if i understand this; some global switch would do most of 
the trick i assume

well, since i want to be able to control consistency, i do need to look 
back; say that the design says: no empty lines (parskips) before something, 
then i need to configure that particular display instance to ignore the 
(possiibly already applied) parskip; keep in mind that it's not always the 
author who decides that somethign should start like a new paragraph; so, 
even if i provide you thsi display feature, i need it to be configurable in 
many ways for my own needs -)  would not hurt you anyway

i cannot simply before=\startdisplay things because it would break 
compatibility, so it would mean that each environment would get a 
display=... switch with some global default, in addition to start/stop

hm, i like a more general view on 'display': anything that stands out in 
the text stream, being par or not, this is why it should be configurable 
(even tex is a bit fuzzy about it, since display math is used for both 
in-par or between par math)
