One possible problem with that approach would be applications that try to
reach machines by name. If a machine is repurposed and you did not use
CNAMES or forgot to repoint a CNAME you could have programs reach a machine
that is no longer doing what the program expects.
Example: You have some type of "inbox" machine that gets data through FTP
from process X. Target machine for process X is re-purposed, but it also
accepts FTP with the same user/password. Now process X is silently broken
because the sender is succeding on FTPing, but whatever was supposed to
process the incoming files is looking somewhere else.
I guess that with the proper change management any method will work.
I think on a company with weak change management it may be easier to have
something fail when a machine is repurposed and renamed.
