I double-checked this, it fails in conncheck. Here are my steps:

# ipa-server-install --setup-dns
# ipa-replica-prepare replica.example.com --ip-address=192.168.100.2
# ipa host-del replica.example.com

On replica, set DNS to IPA master, with hostname in /etc/hosts.

# ipa-replica-install ...

The verify_fqdn() passes because the resolver uses /etc/hosts.

The conncheck fails:

Execute check on remote master
Check connection from master to remote replica 'replica.example.com':

Remote master check failed with following error message(s):
Could not chdir to home directory /home/admin: No such file or directory
Port check failed! Unable to resolve host name 'replica.example.com'

Connection check failed!
Please fix your network settings according to error messages above.
If the check results are not valid it can be skipped with 
--skip-conncheck parameter.

The DNS test happens much further after this, and I get why, I just 
don't see how useful it is unless the --skip-conncheck is used.

ipa-replica-install ~rcrit/replica-info-replica.example.com.gpg 
--skip-conncheck
Directory Manager (existing master) password:

ipa         : ERROR    Could not resolve hostname replica.example.com 
using DNS. Clients may not function properly. Please check your DNS 
setup. (Note that this check queries IPA DNS directly and ignores 
/etc/hosts.)
Continue? [no]:

So I guess, what are the intentions here? It is certainly better than 
before.
