Product Decisions This Supports

Dependency modernization and upgrade planning: Flags prologue/support as an abandoned 2015 dependency, supporting a decision to block new adoption and schedule replacement before Laravel/PHP upgrades.
Build vs. buy: For extended Illuminate\Support helpers, favor native Laravel APIs, a small in-house utility, or a maintained package over this abandoned extension.
Technical debt prioritization: Low adoption (15 stars) and no releases since 2015 indicate no community support, bug fixes, or security patching; this supports backlog prioritization for removal.
Legacy support decisions: If already installed, supports a replace-or-remove decision rather than expansion into new features.
Use-case fit: Historically covered convenience extensions to Illuminate\Support (helpers/macros); modern Laravel already covers most of these needs natively.

When to Consider This Package

Only in an existing legacy Laravel application where it is already installed, pinned, and working, and where immediate removal is riskier than temporary retention.
As a short-lived migration shim while moving helper logic to native Laravel or a maintained package.
Not for new products, new features, modern Laravel/PHP versions, or any application with security and maintenance requirements.
Look elsewhere for maintained alternatives: Laravel’s native support utilities, spatie/laravel-collection-macros, or a small internal helper package.

Executives: This is an abandoned, low-adoption dependency; do not add it. Treat it as technical debt and plan removal to reduce maintenance and security risk.
Engineering: Avoid new usage; audit existing references; replace with native Illuminate\Support features or a maintained package; keep any legacy shim temporary and documented.
Product: No roadmap investment. Allocate small maintenance capacity for dependency cleanup rather than feature work.
