>> Yes (-ish). The compression level is now a part of the pdf back-end

>>> Sometimes it makes sense to have some parts uncompressed

>> You could just be brave and not compress the pdf at all.
> There can be Metadata Streams in the PDF file (e.g. in the
> Catalog). The PDF specification says in "10.2.2 Metadata Streams":
just a thought - if cleanup for making \pdfcompresslevel static makes
the code simpler ("The compression level is now a part of the pdf back-end
structure ..."), maybe there could be an option in the \pdfobj to force
a particular stream to have no compression, instead of making
something like \pdfobj stream nocompress ...
