A scuttle valve seems like a sensible inclusion. Lacking that, remember that it would be a much more comfortable death to run out of oxygen before the CO2 absorbent expires, since you have no hope of getting out. Design your life support durations accordingly.

We have all been there with something or other, where we thought the best
thing to do was to break the window to get back in the house or car, or
gotten off the trail thinking camp was that way, or damaged something or
other and only in hindsight seen that I didn't have to do it that way!
Why inflict permanent damage on your sub and possibly yourself, and at the
same time leave a years wages at the bottom of the ocean.
Look at the sub incidents in the past.
