No.
No ABI change means no new symbols in the public header files, no
changes in manual pages and no 'backwards compatible' changes. No
ABI changes at all.
Only mainline can have ABI changes, and the -stable should be
completely compatible up and down all stable releases. Compiling
against 15.9 should continue to load and work with the same feature
set 100%.
Anything else is madness and people will start to ask for backpointing
features and other crazy things to -stable.
