Yes, the text you quoted below is relevant to this point.

I already suggested changing "special purpose values" to "reserved or
special-purpose values".  I think that might be enough to cover my
earlier concern.

However, I also think we should mention that the ranges are subject to
change.  The IETF may decide to reserve something that's currently
unused but within the range delegated to the RIRs, or the IETF might
decide to release some previously-reserved space for general use.

Here's a suggested rewrite to include this issue.

    The specific registries that are administered by the IANA per
    the authority delegated to the Internet Number Registry System
    are "Autonomous System (AS) Numbers", "IANA IPv4 Address Space
    Registry", and "IPv6 Global Unicast Address Assignments".  These
    IANA registries also contain information about reserved or
    special-use values or ranges that are outside the management of the
    Internet Numbers Registry System and instead administered under the
    direction of the IETF.  The delineation of the specific reserved
    ranges and ranges delegated to the Internet Number Registry system
    is provided in RFC 7249.  It is expected that the boundary between
    IETF-managed and Internet Number Registry-managed parts of the
    number spaces may change from time to time, with agreement between
    the IETF and the RIRs.  Possible reasons for changes include the
    possibility that the IETF may release some previously reserved space
    for general use, or may reserve some previously unused space for a
    special purpose.

This might be a good place for us to mention the idea of an MoU between
the IETF and the RIRs.
