The answer to this is actually clear cut.
IF gender recognition is a human right at all (my own view is that it is not, that the Goodwin case was bad law and an example of political meddling by the ECHR), it is not a standalone human right. It is considered to form part of the right to a private and family life, which is a qualified right.
People have quite often tried and failed to invoke this right, often in an immigration context. The UK has not been declared non-compliant with the ECHR because it does not automatically grant visas to the partners and families of British citizens, for example. The logic is that a person's right to bring their spouse or family members to live with them in the UK must be balanced against the need to protect the UK population as a whole by having a robust immigration system.
So the "right" to gender recognition could never be considered absolute and should in theory be balanced against the rights of any other people who could be affected by it.
Goodwin really was a terrible piece of jurisprudence. The facts of the case concerned the right to marry. A trans person claimed that their right to a private and family life was being infringed because they were not allowed to marry their (same sex, opposite gender identity) partner. And instead of saying, "the right to a private and family life should include the right to marry any single and consenting adult, regardless of sex or gender identity" the batshit judges decided that the right to a private and family life should include the right to change your legal sex so that you could become the opposite sex to your partner and therefore marry them.
As a result, trans people with a gender recognition certificate got the right to marry their same sex partners over a decade before ordinary gay men and lesbians did. (OK, the Civil Partnership Act was passed at around the same time, which gave all the same rights as marriage, but arguably not the same social status.)
Remember this, any time someone tries to tell you that trans people were front and centre of the fight for gay rights, and that a trans woman threw the first brick at the Stonewall riots. There must be no LGB without the T, but there's been plenty of T without the LGB. I do not recall any trans people standing up after Goodwin and saying, "Hey! What about the rest of the LGBT community?"
Edit: Will my phone fucking stop autocorrecting LGB to LGBT, thus proving my fucking point?
