I don't see any merit in using prefixes with degrees Celsius (regardless of
the fact that the SI Brochure allows them).

The everyday use of Celsius temperatures, which is over a fairly limited
range, requires neither extreme precision (millidegrees) nor great magnitude
(kilodegrees or megadegrees).

Where high precision or great magnitude are required (typically in
scientific applications), I believe it's much better to used the kelvin.
And, of course, mK would only be used for temperatures or temperature
differences of less than 1 K. Actual temperatures would be in kelvin,
kilokelvin and megakelvin, using numbers to the right of the decimal point
where high precision is warranted.

Without prefixes, of course, the customary absence of a space before the
degree symbol isn't a problem.
