[db-wg] Questions about status: LEGACY

Could someone be so kind as to enlighten me about the intended semantics
of "status: LEGACY"?

I'm back to trying to do parsing of the data base, en mass, and I've
just now noticed that the annotation "status: LEGACY" within a given
inetnum record may not mean what I thought it meant.  (And by the way,
there seem to be several tens of thousands of inetnum records in
the data base, at present, which are all marked as "status: LEGACY".)

Here are just a couple of randomly chosen samples that are confusing me:

inetnum:        51.155.0.0 - 51.155.255.255
netname:        UK-ZEN
descr:          Zen Internet Limited
country:        GB
org:            ORG-ZIL1-RIPE
admin-c:        RT1337-RIPE
tech-c:         ZIRA1-RIPE
status:         LEGACY
mnt-by:         RIPE-NCC-LEGACY-MNT

inetnum:        51.155.91.64 - 51.155.91.71
netname:        ZEN20210525-NOC-NYCOMM-LIMITED
descr:          Nycomm Limited
descr:          leased-line
country:        GB

In what sense is the first inetnum record above denoting a "LEGACY" block?
The block appears to have been first assigned by RIPE to ORG-ZIL1-RIPE
on 2015-09-23.  Aren't LEGACY blocks just the ones left-over from the
very old days?

I have the same questions also for the second inetnum record shown above,
which is a sub-assignment / sub-allocation of the first one.

Well, here's another one.  This also seems rather un-LEGACY, based on
the apparent creation date.

inetnum:        162.55.0.0 - 162.55.255.255
netname:        DE-HETZNER-19920803
country:        DE
org:            ORG-HOA1-RIPE
admin-c:        HOAC1-RIPE
tech-c:         HOAC1-RIPE
status:         LEGACY
mnt-by:         RIPE-NCC-LEGACY-MNT
mnt-by:         HOS-GUN
mnt-lower:      HOS-GUN
mnt-domains:    HOS-GUN
mnt-routes:     HOS-GUN

I'm sure that there is a perfectly rational explanation for all of this.
I would greatly appreciate it if someone would guide me to it.

Whatever is going on here, I obviously didn't get (or didn't read) the memo.
