Ok, there is a (temp) root exploit based on CVE 2015-1805 for Sony Z* line now: forum.xda-developers.com/crossdevice-dev/sony/iovyroot-temp-root-tool-t3349597 (source at github.com/dosomder/iovyroot)

I will probably downgrade my Z5 compact to LP this evening and try it out (backup/downgrade/root/backup-TA/pre-root-FW/upgrade/restore...)

Note: this exploit works perfectly on Sony Xperia Z5 compact firmware 32.0.A.6.200, incl. backup/restore TA partition (verified personally)
