mammaleh – it may be possible to be adaptive but I ate by people who gave me matzo in a bag and i found it to be not only uncomfortable, but i felt it was an inappropriate way to perform the mitzvah. It is not my mesorah and i don’t feel it was bkovodik. I may be able to adapt, but i wouldnt want to. Its not comfortable for everyone just because its comfortable for some.
In the same way that my husband would not possibly feel comfortable staying by a chassidish friend and venturing to shacharis at 9:45.
It isn’t just different, it wouldn’t feel appropriate.
and on the funny side – i thought the matzo bags were for putting your matzo sandwhich in since a sandwhich bag is too small!
