question: about the goal of migrating better bip32 methods for deriving secrets

[trueptolemy]

I find this in hsmd.c :

/* FIXME: lnd has a nicer BIP32 method for deriving secrets which we should migrate to. */

It was marked above hsm_channel_secret_base(&channel_base).

In order to be a qualified thief, I went to lnd's source code and found it depends on a golang package--waddrmgr to achive a HD wallet based on BIP0044.
In this package, the process of driving secret base from a seed is similar with c-lightning, but the highlight of their HD wallet is the implement of BIP0044.

Thus, I guess "a nicer BIP32 method for deriving secrets" indicates the implement of BIP0044, which can manage HD addresses elegantly.

I am not sure if my understanding is correct. ping @rustyrussell
