10 Yes, it is indeed extremely annoying. As a KDE-4 and e17-svn user I'm all too
11 aware.... But you have to consider the actual cost of a technique designed to
12 increase convenience where the results are not determined.

21 "Which is not influenced" - this is the crucial clause, the one that is
22 fraught with error. Who is to say what "not influenced" actually means? A
23 complete lack of any related dependencies is one workable way to scope it. It
24 happens often enough that it's worth the effort to accommodate it.
26 But it also represents an alternate unexpected code path and for that reason I
27 believe it warrants a configuration option but not to be default. IOW, you
28 have to ask for it to get it.
30 If you haven't already guessed, I subscribe to the school of thought of "Don't
31 Cause Unintended Side-Effects"
