Apparently not - if you try the same with 'Compression no' and
'compression no', it works as expected; it you use incorrect option,
you get the proper error message. For whatever reason it recognises
[Cc]ompression option, but not the value of the option:

$ ssh -F /dev/null -o "Compression no" localhost
Password for xci@ymir:$

$ ssh -F /dev/null -o "compression no" localhost
Password for xci@ymir:$

$ ssh -F /dev/null -o "compression yes" localhost
command-line line 0: unsupported option "yes".

$ ssh -F /dev/null -o "Compression yes" localhost
command-line line 0: unsupported option "yes".

$ ssh -F /dev/null -o "Compressionx yes" localhost
command-line: line 0: Bad configuration option: compressionx

$  ssh -F /dev/null -o "Compression x" localhost
command-line line 0: unsupported option "x".     #  same as when 'yes' is used.

Same happens if the option is specified in .ssh/config file, instead
on the command line.
