Can you take a look and see if this has the desired effect?

It doesn't seem to fix $world. I think that for most packages the tighter relationship is coming from symbols, i.e.:

 __x86_get_cpuid_feature_leaf@GLIBC_2.33 2.33
 fstat64@GLIBC_2.33 2.33
 fstat@GLIBC_2.33 2.33
 fstatat64@GLIBC_2.33 2.33
 fstatat@GLIBC_2.33 2.33
 lstat64@GLIBC_2.33 2.33
 lstat@GLIBC_2.33 2.33
 mallinfo2@GLIBC_2.33 2.33
 mknod@GLIBC_2.33 2.33
 mknodat@GLIBC_2.33 2.33
 stat64@GLIBC_2.33 2.33
 stat@GLIBC_2.33 2.33

or shlibs:

ld-linux-x86-64 2 libc6 (>= 2.33)
libBrokenLocale 1 libc6 (>= 2.33)
libanl 1 libc6 (>= 2.33)
libc 6 libc6 (>= 2.33)
libdl 2 libc6 (>= 2.33)
libm 6 libc6 (>= 2.33)
libmvec 1 libc6 (>= 2.33)
libnsl 1 libc6 (>= 2.33)
libnss_compat 2 libc6 (>= 2.33)
libnss_dns 2 libc6 (>= 2.33)
libnss_files 2 libc6 (>= 2.33)
libnss_hesiod 2 libc6 (>= 2.33)
libpthread 0 libc6 (>= 2.33)
libresolv 2 libc6 (>= 2.33)
librt 1 libc6 (>= 2.33)
libthread_db 1 libc6 (>= 2.33)
libutil 1 libc6 (>= 2.33)

Not denying that this might fix some things (packages which build udebs themselves), but I'm not sure making the claim about "any packages built in proposed" getting a too-tight relationship is right.
