I also hate the way the credits appear to jump back a few frames just before the squeeze begins causing a noticeable nasty judder.
Yep - that is just poor implementation in the playout area (to save money) - which is an insult to the audience. The thinking these days goes "Joe Public won't notice" - which is condescending to our audience. The same thinking is behind the reduction in resolution of services on satellite and Freeview (loads of channels are now 544x576 not 720/704x576) and the ever increasing levels of compression.
The jump is caused by the digital video effects (DVE) box that does the shrink being switched into circuit. To do the squeeze it has to add at least one (sometimes more) frames of delay and the switch point is always obvious - as you couldn't chose a signal more obvious to highlight the delay than a rolling caption. If they played the programme out through a matched delay, and fed the DVE with a pre-delayed feed it would be transparent...
Other ECP styles that overlay rather than squeeze or reposition are transparent because they don't need to delay. If the credits were mixing cards rather than rolls or crawls you'd also not see the delay.
