Will the glue breakdown? Sure, eventually ... in a 100 or so years. Look at vintage furniture using hide glue. These pieces are not intended to last 100 or more years. Fashion will see to that. So ... okay for this situation, not-okay for stressed joinery.
With regard to mitres and biscuits et al, a big reason they are used is to prevent movement when glueing up. Glue is slippery and a misaligned mitre is ugly. Glueing a mitred joint is tricky. The tape method I used here is fantastic for alignment, better than anything else out there. And easy.
