I tend to agree about that.......What I never do is stand on the pegs to mount any bike, it just doesn't feel stable - probably just me but there you go!
In fact i'm not 100% sure that an aluminium side stand that's already supporting a 350kg bike has the safety margin to consistently take the added strain of me + leathers (...say 135+kg), but some aspect to that is what angle the bike is leaning and how heavy handed I might be, climbing aboard etc..
That's why I tend to do either the 'John Cleese method' or the resting the knee on the seat and holding the lower leg back against my upper leg to clear the luggage.
The John Cleese method is my default method, but I can imagine it's not for everyone.
When I owned a KTM 990 Adventure S, and rode with a lot of luggage, that was a bit of a challenge, but If the curb height was significant enough, I could still do it. If not, then i'd put it on the centre stand and clamber aboard via the foot rest. Mind due, the bike was so tall on the centre stand I sometimes found it almost impossible to push it off the stand while sitting astride the bike.
