The rumored RF 18-45 would fit the bill for a crop standard zoom, if a bit short on the long end, and the already-released 70-200/100-500 would be great long telephoto lenses on crop. They need to do something about the 45-70mm gap, though: carrying an 18-45 and 24-70 or 24-105 together doesn’t sound terribly elegant.
An 18-45 with an APS-C image circle would be totally underwhelming, and underwhelming is not what we need for a high-end crop body. This is one rumour which doesn't make any sense to me. If the rumour mill has got it wrong and this is in fact an entry-level ultrawide option for full frame (in the same spirit as the EF-S 10-18 for crop DSLR) then I can see how it would be credible.
Rumors suggest that the 18-45 is going to be a full frame lens: a consumer-grade ultrawide zoom for full frame users, a standard zoom for crop users. In other words, a successor to EF 17-40L. If its optical quality on full frame is at least comparable to EF 16-35F4L while being much smaller, I'd certainly give it a thought even if I never buy a crop RF body. 16-35F4L is rather long when mounted on the R with an adapter.
Rumours are just that of course. Canon has an old patent (i.e. not a rumour), reported in 2012, for an 18-45 f/3.5-5.6 for APS-C mirrorless: https://www.canonrumors.com/canon-18-45-f3-5-5-6-kit-lens-for-aps-c-mirrorless-patent/ . The exact same zoom range could be a coincidence of course, but it could have formed a (flimsy) basis for the more recent rumour.
But my main point is that it would be a rubbish standard zoom for a high-end crop-sensor RF body and I absolutely stand by that.
Well, if you go around discounting rumors just because they are rumors, we are gonna have to call off the entire thread because an APS-C RF mount body itself exists only in rumors.
As for the last paragraph, do you remember which zooms were bundled with 7D mark II? I do, because I bought one. I had the choice of EF-S 18-135 F3.5-5.6 STM, not a high-end zoom by any means, or EF 24-70F4L, which is high(er)-end and certainly built to match 7D2's weather sealing, but lacks the right range for crop. I'd be surprised if Canon showers any more love on the bundled lens for the rumored APS-C RF body than they did on the 7D2.
