Thanks, looks good.

Could: It feels like there's some general tidying up we can do here, but maybe that would be easier after the other moves to using the config server. For example:

• Why do we have a separate MX config server client that we use sometimes?
• The way we patch "dodal.common.beamlines.beamline_parameters.BEAMLINE_PARAMETER_PATHS", in mx-bluesky is quite odd in that we use i03 for everything and we just patch it all the time rather than patching what we need when we need it

[DominicOram]

Should: Can we not combine this and _fake_config_server_read?

[jacob720]

We have an MX config client which directly reads the the filesystem if the server is down. I think this is no longer viable since the server now does conversions, so we'd have to build that same functionality into the MX config client. Discussed with @olliesilvester a few times and we came to the conclusion we'd delete this, particularly as i03 are happy to use the config server for Hyperion now it's deployed on their beamline cluster.

I think you're right though, it would be easier to do this and other tidying once all the config server PRs are in.
