in the main .. no, they don't need it.
the 'hi-quality' settings are only really applicable to effects which, through their processing take the available frequencies up above nyquist (half the sample frequency) . If a frequency goes above nyquist then it produces aliased versions of those high frequencies, these aliases come reflecting back down into the audible - but they will be scattered un-musically.
Certain effects really shift the available tones above nyquist very easilly, for example - the saturator is a wave-shaping effect which creates extra harmonics above the ones you provide. Obviously 'above' means that any input with high harmonics will probably enable an un-over-sampled waveshaper to produce aliasing. In the past Saturator was not oversampled, but over sampling was added. To preserve the sound of old sets a 'legacy mode' was provided through the use of a 'high quality' menu option switch.
Of course - in newer effects, where there has never been a legacy, there is no need for a legacy mode and a switch has not been provided.
To answer your question directly though, as I wandered off topic.

Effects like Delay, or beat repeat, or the Looper don't need oversampling - because they are very unlikely to take a 10khz harmonic and do something horrible with it, such as transpose it up through the nyquist barrier.
Other effects could benefit from oversampling, for example the 'autofilter' would be very pleasant with a few more filter types and an oversampled Ladder in there. But in the main - the ones which have Oversampling are the ones that really really need it, the ones which do not are the ones where it would be a 'nice add on'
Having said all that, it's pretty moot anyway, as anyone that bases their estimates of Lives sound quality on AutoFilter's oversampling is looking in the wrong place anyway eh?
EG: Does Cubase still offer "Wunderverb" ? (which was the horriblest effect I ever heard) and does that make Cubase 'sound bad' ?
