Sometimes I will use Fable or Sol for large features/projects, or research/exploration.
I would not be at all happy if I were forced to use Luna, though. I’d probably start looking to leave. I don’t want to work somewhere where I don’t have choice over my tools.
As long as there is no cost involved there is little reason to restrict such tooling, but expecting your employer pays non-trivial sums is likely to raise questions about whether that extra cost is worth it. In this case, is the delta from luna to sol worth the extra order of magnitude in cost. If it's $2 a day vs $20 a day then there should be little discussion, but at $50 a day vs $500 a day, the question seems relevant.
It is not reasonable for a company to pay a fully loaded engineer >$40k/mo and then ask them "why did you need $500?" on some odd days where they are doing difficult work, large refactors, experiments, etc.
