You know a whole the size of a quarter can wreck the entire spacecraft and make it effectively throw away? Also, you'd want to use this many times. Making a system robust while not requiring months of refurbishment is really really hard.

Now they do, as a matter of course.
Being a cynical naysay isn’t hard.
The quarter thing may have been true for the space shuttle, that doesn't make it true in general.
