I fail to understand the reason for this concern about temperatures stated in degrees Celsius versus temperatures stated in kelvins. Both are SI units and both temperature scales are recognized. The degree Celsius is a derived unit (Table 3 of the brochure); nothing is said about derived units being less desirable or "less SI" than base units.
The liter is a very slightly different matter, since it is not an SI unit. Nonetheless, it is accepted for use with the SI (Table 6). This discussion thread reminds me of linguistic purists who turn their noses up at contractions and who quibble over "shall" versus "will".
