WG] For some values of "fine" and "great" perhaps, but emphasis on the
"lightweight" is important, as its suitability is heavily dependent on
your intended use case.
Use it with a few thousand routes and nothing particularly exotic as far
as features go and you should be fine. However, there are sometimes little
gotchas where established features (esp in MPLS) either are missing or
behave differently in subtle ways compared with more traditional JunOS
routers like the MX. Some of these are limitations in the Broadcom chipset
and some are driven by customer demand prioritizing feature completion.

Test carefully, and regard the higher-end multidimensional/route scale
numbers with healthy skepticism.
