PSScriptAnalyzer disapproves the construction of any case sensitive hash table

[iRon7]

The UseLiteralInitializerForHashtable should prevent programmers to inconsiderately build hash tables with a default comparison other then the default case sensitive PowerShell behavior. It should not prevent a programmer from building a case sensitive hash table at all.
Hash tables are often used to handle program data but they might also be used to store custom input data (whether or not case sensitive) and the desired output might highly depend on the customer's used-case.

In other words, it is good that I get a warning on

$hashtable = [hashtable]::new()

and:

$hashtable = New-Object -TypeName hashtable

But if I well-considerate explicitly set the comparison mode, like:

$hashtable = [HashTable]::New(0, [StringComparer]::Ordinal)

I expect the warning to be suppressed.

see also: How to create a case sensitive Hashtable without generating a PSScriptAnalyzer warning?

Steps to reproduce

Invoke-ScriptAnalyzer -ScriptDefinition '[HashTable]::New(0, [StringComparer]::Ordinal)'

Expected behavior

No warnings

Actual behavior

Use literal initializer, @{{}}, for creating a hashtable as  they are case-insensitive by default

Environment data

PSScriptAnalyzer version: 1.18.3
Tested both Windows PowerShell (5.1) and PowerShell Core (6.2.3)

The rule does not complain about cases where the [StringComparer]:: value ends with IgnoreCase, for example
[HashTable]::New(0, [StringComparer]::OrdinalIgnoreCase)
Why would using Ordinal make the hashtable case insensitive? This seems to be by Design because Ordinal is a case sensitive string comparer

[iRon7]

The underlying question remains: how do I create a case-sensitive hash table without causing a PSScriptAnalyzer warning?
I have a hard time to accept that constructing a case sensitive hash table should be avoided in general, I think that PSScriptAnalyzer should just prevent that someone from inconsiderately constructs a hash tables with a default (case-sensitive) comparison...

You would suppress the rule for the function where you create that hashtable because you know what you are doing. This is what rule suppression is for
