I can't say I've mastered the rules of RFC 4235, or rather, RFC 3840, which is what is driving this. But the "+" and "sip." prefixes seem to be intended to disambiguate things, to prevent tags of different sorts but the same names from being mistaken for SIP feature tags. So I would say not to be tolerant, but to expect each tag to be represented correctly in each context -- because things that look like badly represented tags are actually something else.
