No. I worked with the author of those patches to make an improved version (that has proper CFI and does not need a soft frame pointer any more, and also can display local variables correctly in more - but still not all - cases). This improved version is included in current SDCC. However it also requires newer versions of the patches to binutils and OpenOCD. So if you want the setup as currently documented at https://stm8-binutils-gdb.sourceforge.io/ you'll have to use SDCC 3.6.0 with the patches there for the versions of binutils/gdb and OpenOCD documented there. If you want the current bleeding edge, you use the current development version of SDCC with the new patches to binutils (and a corresponding binutils version) and the current development version of OpenOCD with the new patches (http://openocd.zylin.com/3952 and http://openocd.zylin.com/4265). I assume that the documentation https://stm8-binutils-gdb.sourceforge.io/ will get updated after the SDCC 3.7.0 release, and hope that OpenOCD will merge the patches before their next release. That would make the use of STM8 debugging considerably easier: One could use out-of-the box SDCC and OpenOCD and would only need a custom gdb.
