user126793: Command help getwalletinfo tells:

"hdseedid": "hex", (string, optional) the Hash160 of the HD seed (only present when HD is enabled)

I understand that sharing this number will result in an immediate loss of funds, because this looks like should enable recreating the whole HD tree. Am I wrong and why?

You're wrong. It is the hash of the seed, not the seed itself.
