Tell that to the cagers on my street that don't even pretend there is stop sign - makes it hard to pull out at all.
OP I'd say it's very good practice to come to a full stop foot down and concentrate on being smooth. If you do a slow rolling you lose that chance to practice those slow skills to and from full stop.
There is no problem looking down to concentrate - don't split your attention as there will be intersections out in the back roads and even not so back roads that are multiple camber and chock full of nasties, holes, rocks, sand and gravel ( Steeles and 9th line is one ) and you need to be able to come to a safe stop on those - that's where the repeat smooth and balanced on the easy ones will come in handy.....and the concentration.
There a few up in Halton that simply are nasty, downhill, off camber and restricted visibility.
Concentrate on the stop.
THEN look for the cross traffic.
my 2¢ I took 10 years off on a 43 year riding span and it took a while to get smooth on odd ball stops....the Burgman weight is low down so it's pretty forgiving but the damn thing is heavy. Get used to your rear brake as well as it's important for wet or loose surface stops.
Have fun ...get out there.
BTW I'm certainly no saint on full stops.....waste of gas

BUT there have been a couple of times when I've been surprised by a cager coming too fast over a crest on a rural intersection.
So unless it's obviously clear in all directions I'll come to a balanced or foot down stop.
Given cops penchant for rolling stops I've seen - they should not be handing out tickets for balanced stops.
On a wide open full viz intersection I'm certainly not coming to a full foot down stop but find it fun to come to a balanced full stop - hold it for a sec and then roll on. It's just good practice.
