Just so, and Blue Sun's ability to run larger ice in a rush deck style helps a lot, I think. After all, you can go broke on defence and still have enough credits to score your whatever-it-was.
And yeah, if you're running Blue Sun and not Taurus, Shattered Remains, or something like that... why not? I mean, hell, Shattered Remains might cost a couple clicks/credits every so often, but you can reveal it, return it to your hand, and then IAA something else. (Super mindgamez play: keep doing that with Shattered Remains until out of money.)
Anything that Supermodernism likes, I think Blue Sun likes even more. An ability to keep your servers threatening/fluid, easier access to decent ice than GRNDL with more stability than BABW... what's not to like?
