I understand why many will desire for it to be a static key in the thumb area, but (1) it definitely is not true that everyone (or even most) will want that, and they should have the option to use the more intuitive behavior this patch offers and (2) even if you want to be able to use it with your thumb so that you can continue movement, space is a pretty undesirable key to have it on, so it should, at minimum, be bindable to a custom key if you want that key to be static instead of dependent on the ability. Goo Ball already had this behavior even before today's patch specifically because you also need to be able to jump during it, so that default bind (space) already didn't work there.
