This is an oversight in the MARC to MODS mapping and stylesheet based on it, not a change proposal for MODS itself. The mapping should map 648 to <subject><temporal>. We will correct both these documents.
It is the case that we included it (i.e. 148) in the MADS mapping as mads:authority/temporal. So certainly it should be in MODS.

Up to now, MARC 648 (Subject Added Entry-Chronological Term) seems not
to be mapped to MODS. The MARCXML entry
<datafield tag="648" ind1=" " ind2="4">
gets transformed by MARC21slim2MODS3-3.xsl to
which is invalid. Since this kind of entries is quite common in our data
(> 10% of the records), it would be great to have them in MODS too.
