you always have the possibility that a new (security) update may come 
with breaking chnages and that extensions stop working well.
so you can get no warranty for any future versions.
the question may be: what version-dependency will be accepted when the 
extension is to be installed.

I would like to see the version dependencies of an extensions be solid 
about which versions of TYPO3 have been tested and I can decide if I 
ignore the dependency and use an extension 'out of range'

so a valid dependency declaration on uploading an extension to TER would 
only be the latest released version.

for searching the TER it would be optimal to have the possibility to 
select a version-range for compatibility of extensions
	on typo3.org default to the latest LTS,
	and in an installation set to the current main version:
		4.5.*, 6.2.* or 7.*.*

and while installing an extension there might be a warning about version 
mismatch, but no strict prohibition, where you need to patch the version 
dependency to get it installed anyway.
