Section 5.2. says:

Length:
8-bit unsigned integer.  The length of the option
(including the Type and Length fields) is in units of
8 octets.  The minimum value is 2 if at least one
domain name is contained in the option.  The Length
field is set to a multiple of 8 octets to accommodate
all the domain names in the field of Domain Names of
DNS Search List.

It should say:

Length:
8-bit unsigned integer.  The length of the option
(including the Type and Length fields) is in units of
8 octets.  The minimum value is 2 if at least one
domain name is contained in the option.  The Length
field is set to a multiple of 8 octets to accommodate
all the domain names in the field of Domain Names of
DNS Search List.

The exact maximum value supported by a given network
is dictated by the MTU of the link, because the
Router Advertisement MUST NOT be fragmented as per
RFC6980#section5. The lowest possible MTU of 1280
results in a lower bound for the maximum value of 148
(representing 1192 octets).

Notes:

While the submitter's point is valid, there is not much that can be done on a per-option basis. Even if this option is sized so that it does not result in the fragmentation of the RA message, there might be other options that do. That is why the restriction for non-fragmentation is specified in a separate document and not in each document that defines an ND option.
