I usually also tend towards just doing - but this time, with LIDAR
it's probably a good advice to think and discuss first
It's really a tricky thing. See e.g. Paul Ramsey's Talk at FOSS4G

P.S. BTW there is another "battle field" over at the format definition
side which currently needs some attention:
