Isn't that what the JunOS EEOL (extended end of life) releases
should be (or more probably could be)?

Juniper already have these releases they guarantee to support for 3 years.

All (!?) they would need to do is to release more 'R' releases of those
versions than they currently do, rolling all bug fixes that are going 
into new releases into the EEOL releases too.

I agree with you that this would keep a lot of their customers happier - 
particularly with the expensive hardware uplift (new CF and RAM for every
RE) that's needed to go from 8.5 to 9.x.

I personally would be happier with the release cycle being halved - if a
new release only came out every 6 months, but each release was better tested
and supported, then I think the end result would actually be a better product.

Currently the general opinion is that an 'R1' release is usually too unstable
to be usable, which means that there isn't really a usable release happening
every 3 months anyway. Slow the whole release process down, and there'd be a lot
more time to test things properly.
