I wonder exactly the same thing:

Why get rid of a mature, versatile system, already in libc under an
acceptable license and size, that even currently does a good job at
maintaining the lastlog without the sparse file issues?  I also expect
db(3) to be used by third parties, as it's been part of BSD for a long
time (and db4 is under a more restrictive license)...

Do we have kernel support for efficiently detecting file system holes,
and are our copying/moving/archiving tools dealing gracefully with
sparse files by default (unlikely)?
