'inline-signing' might go away and be replaced by dnssec-policy ?

i've read this comment

> 'inline-signing' might go away and be replaced by dnssec-policy

now a few times, in posts and in docs

currently, WITH 'dnssec-policy' signing enabled & in-use, i've

	zone "example.com" IN {
		type master; file "namedb/primary/example.com.zone";
		dnssec-policy "test";
		inline-signing yes;
		...

the 'inline-signing yes;' is needed IN ADDITION to 'dnssec-policy' in order to _not_ overwrite original zone files/data on signing.  e.g., with the config above

	cd namedb/primary/
	ls -1 *example*
		example.com.zone          <==== THIS is the original, unsigned zone data
		example.com.zone.jbk
		example.com.zone.jnl
		example.com.zone.signed   <==== THIS is the signing-generated zone data, which gets propagated
		example.com.zone.signed.jnl

without it, the original "example.com.zone" is overwritten with signed data.

is there already config in, or planned for, 'dnssec-policy' that preserves that separate-file functionality, preserving the original?
