[Verse 1]
When access control's not your main need
XACML won't plant the right seed
If you're building apps that need to flow
This heavyweight just moves too slow
[Verse 2]
Cedar's got the same limitation
Access control's its only station
When your policies need to expand wide
These tools will leave you unsatisfied
[Chorus]
Not the right fit, not the right time
When your needs don't match their design
Verbose and heavy, slow to change
When lightweight's what you need to arrange
Know where not to go
That's how expertise will grow
[Verse 3]
XACML's verbosity shows
When rapid evolution flows
Organizations moving fast
Find this framework holds them back
[Verse 4]
Emerging hybrid paths appear
When single tools can't solve what's here
Part five reveals the modern way
Blending approaches for today
[Chorus]
Not the right fit, not the right time
When your needs don't match their design
Verbose and heavy, slow to change
When lightweight's what you need to arrange
Know where not to go
That's how expertise will grow
[Bridge]
Management controls need the right tool
Don't force a fit, that breaks the rule
Access only, that's the boundary line
Step beyond and you'll need to redesign
[Outro]
Formal languages, pick with care
Match the problem to what's there
When it's not useful, walk away
Live to code another day
