To add an example to what I posted above:
There is a svarah brought in halacha sfarim, (I don’t remember where, its possible it’s in igros moshe, but I think earlier than that as well) that although the halacha is that if you didn’t have kavanah for the first line of Shema, you must repeat it, nowadays you should NOT not repeat it, because nowadays we anyway do not have proper kavanah, so its better to not repeat it.
Meaning, nowadays the best thing to do is not to go back, because we anyway don’t have kavanah. At the same time. that is not the ideal; the ideal would be to be able to have kavanah, we are just not holding there.
Similarly, nowadays Chabad isn’t holding by sleeping in the sukkah, therefore the best thing nowadays for them is to sleep outside the sukkah (as it causes pain), that being said, the ideal was and still is to be at the level where you can and must sleep in the sukkah.
I know the examples aren’t exactly the same, mainly that in the first scenario you are anyway in a B’diavad, but you get the point.
