Details - validate.c uses inet_pton for identifying IPv6 addresses , and this seems to not understand interface identifiers as used for Link-local IPv6 addresses.
root at FFF-GW-Adrian:~# /sbin/validate_data host fdff::1
host - fdff::1 = true
root at FFF-GW-Adrian:~# /sbin/validate_data host fe80::1
host - fe80::1 = true
root at FFF-GW-Adrian:~# /sbin/validate_data host fe80::1%br-mesh
host - fe80::1%br-mesh = false
This is a problem practically whenever validata_data is used to check uci values.
For example, it is not possible to use a link-local address for specifying an NTP server:
If 'server:list(host)' is changed to 'server:list(string)' there, it obviously works fine, as it's just the validation.
