I don't see any problem with it. Dots are a perfectly valid character in
DNS names. What concerns you about it? Is it because you're not
delegating bloggs.somewhere.someplace.com as a separate zone? Nothing in
DNS assumes that a subdomain is also a subzone. In fact, it's quite common
for it not to be; for instance, in reverse domains for class B networks
it's common to have everything in the same zone, with entries like
1.2 IN PTR host-2-1
3.4 IN PTR host-4-3
