It doesn't seem necesary, as it's use could work exactly like normal ladders.
Though you do get transparency with this idea which is a useful feature for a block to have.
-You can see mobs coming
-Looks nicer in terms of structure compared to placing an entire block and Ladder.
Also this block would have double sided climbing
-could be quite useful if built into a fenced off area. You can quickly get in and out of the are while mobs cannot climb over the block
-no need to click like a gate requires, Also better than a gate since animals can pass through a gate, if you forgot to close it.
Overall many unique and useful features.

You can place ladders on glass as for now, just hold shift and right click the glass.
Your typo is confusing. Also its not a very effective strategy, especially for tall structures.
